dear bhai
i allways respect neat and shiny mehrans as usualy people dont give proper love and attention to them 
u realy dont need compounding
use armorall shampoo
after shampoo use turtle swirls and secratch remover ( give more rubs with less presure on hood where u have more swirls and less light rubs on rest of pannels , it will also remove / minimize the back bumper secratch, its a kind of light polish so will also improve the whitness of ur love ride )
than top up with turtle ice polish
total budget of all these stuff roughly rs 2000 to 2100
will await pic after detailing session with these stuff
